The QR
command finds the QR decomposition of a matrix.
- 
QR takes three arguments:
- 
A, a square matrix.
- q and r, two variable names.
 
- QR(A,q,r) returns the matrix R from the QR
decomposition of A, and assigns the matrices Q and R to the
variables q and r.
Example
The result is the matrix R. To obtain Q:
